PRE-CODING CONTROL INDICATION INFORMATION RECEIVING AND FEEDBACK METHOD, AND THE COMMUNICATION DEVICE THEREOF

摘要

The invention belongs to wireless network communication field, and for resolving the question that the prior art can't realize uplink multiple-input multiple-output (MIMO) from a terminal to a base station, provides a method and device for receiving and feeding back pre-coding control indication (PCI) information while performing the uplink multiple-input multiple-output (MIMO) transmission or uplink Closed Loop Transmit Diversity transmission. Wherein, the base station transmitting method includes a code sequence representing pre-coding control indication information is carried in the feedback channel of the base station. The beneficial effect of the invention is that: by feeding back PCI information, it realizes that the terminal maximizes the block length supported by the existing channel condition after using uplink MIMO, and the uplink transmission rate is increased.
